Find an installer to fit a heat pump cylinder in Northamptonshire
A cylinder with too small a coil can take too long to reheat from a heat pump. Note the height of the cupboard or loft hatch.
Describe your job in Northamptonshire, and up to four independent heat pump businesses may respond, depending on the type of job and where each business operates. Matching costs nothing, and every quote can be declined.
What heat pump cylinder installation involves
A heat pump works at lower water temperatures than a boiler, so it needs a cylinder with a much larger heat exchanger coil to transfer the heat. The installer fits the cylinder, connects the primary flow and return, adds safety and expansion equipment, and sets controls and a periodic high-temperature cycle for legionella protection.
What installers ask about first
- A combi boiler being replaced by a heat pump
- A cylinder that takes hours to reheat
- A family that runs out of hot water
- Limited space or ceiling height
- A desire for a smaller, more efficient cylinder
How installers usually tackle it
The cylinder is usually the last piece to go in before commissioning. A typical job includes:
- Making the heating and water supplies safe before emptying the old cylinder.
- Removing the old cylinder and any redundant pipework or tanks.
- Positioning the new cylinder, checking floor strength, clearance and a safe discharge route.
- Connecting the primary pipework, cold feed, expansion vessel, tundish and discharge pipe.
- Testing the cylinder, controls and legionella cycle, and showing you how to set the temperature.
Vented or unvented, indirect or direct
Most modern heat pump cylinders are unvented. They deliver mains-pressure hot water and need a discharge pipe to a safe place. Vented cylinders use a loft tank and give lower pressure. Your installer should explain why they suggest one, and what size cylinder and coil they have chosen.
What to agree before work starts
Clear the airing cupboard or plant space and tell the installer about hatches, stairs and narrow doorways. Ask who removes the old cylinder, who makes good any pipe holes and whether the discharge route from an unvented cylinder needs a new wall hole.
Cylinder handover
Have the hot water settings demonstrated at handover. Keep the cylinder model, commissioning record and notification paperwork together. Agree who removes the old cylinder and any redundant tanks.
The cost of heat pump cylinder installation in Northamptonshire
Expect something in the region of £1,200–£3,000. Each business sets its own prices. A like-for-like swap of an existing cylinder for a heat pump cylinder sits at the lower end. A first cylinder in a house with a combi, with new pipework and a discharge route, is in the middle. Large cylinders, long pipe runs or moves to a new location take the job to the top of the range or beyond.
Check whether the written price includes equipment, labour, survey charges and VAT. Allow 1–2 days as a guide for the work itself; equipment lead times and awkward access can add to it.
Before you send the form
Say how many people live in the house, how many bathrooms and showers there are, and how big the existing cylinder is, if there is one. Mention the available space, including ceiling height and the width of any door or loft hatch.
Check exactly what the price covers. Ask for the cylinder make, volume, coil area and heat-up time, the controls included and whether a tundish, expansion vessel and discharge pipe are in the price. Check the installer is qualified to fit unvented cylinders.
Rules that apply to the work
Use an installer competent in unvented hot water systems and ask how the work will be notified. Approved Document G for England explains hot water safety requirements there; the other UK nations have their own guidance. Agree the expansion, temperature controls and safe discharge route before fitting. MCS paperwork does not replace any building regulations notification required for the cylinder.
If you are not sure whether the council needs to know, ask North Northamptonshire/West Northamptonshire. If the job grows beyond what was quoted, confirm which approvals apply before the extra work starts.
Getting a business to Northamptonshire
Businesses covering Northamptonshire need the postcode and the nearest town or village. Tell them about permit parking or a tight drive. Photographs of the airing cupboard or loft hatch help an installer judge access. The existing heating matters as much as the postcode, so describe your own system.
Ready to ask for prices?
Use the free enquiry form to describe the job. Give the household size and the cupboard dimensions so the cylinder can be sized and priced to fit. Businesses that join are asked for insurance details and references. Before booking, ask to see current insurance and the qualifications needed for the quoted work. We only pass the enquiry on: advice, pricing and the work itself come from the business you pick.

Roughly how much is heat pump cylinder installation in Northamptonshire?
We use £1,200–£3,000 as a UK guide. Businesses in Northamptonshire price their own work, and the cylinder size, the position and the discharge route affect the total. A written quote should list equipment, labour, VAT and any survey or call-out charge.
Why does a heat pump need a special cylinder?
A heat pump heats water at a lower temperature than a boiler. The cylinder needs a larger coil to absorb that heat quickly. An unsuitable coil can slow reheating and increase reliance on the immersion heater.
What size cylinder do I need?
It depends on the household’s hot water use. Many homes need 150 to 300 litres, but bathrooms, showers and the pump’s output all matter. The installer should explain how they chose the size.
What is the legionella cycle?
A programmed heat-up of stored water to help control legionella risk, sometimes using the immersion element. The installer should set the temperature and frequency to suit the system and manufacturer’s instructions.
How long should I allow for heat pump cylinder installation?
Allow 1–2 days as a guide. Ask for the cylinder volume, coil area and reheat time to be written on the quote. Equipment deliveries, pipework changes and electrical work can add time. Agree how long heating or hot water will be unavailable.
